PLOW.

Specification of Letters Patent.

Patented May 12, 1908.

Application filed February 1731906. Serial 110. 301,669.

To all whom it may cncern:

Be it known that I, J ORGEN H. SYLVESTER- SEN, a citizen of the UnitedStates, residing at Dundee, in the county of Kane and State of Illinois,have invented a new and useful Plow, ofwhich the following is aspecification.

This invention relates to plows; and the object of the invention is topresent a special plow adapted for the purpose of turning back intoditches, such as tile ditches, the furrow slice or material excavated inthe process of making the ditch and deposited at one side thereof; thesaid plow being intended. particularly to be used subsequently to, andas an accessory to, a ditching machine, an example of which may be foundin Letters Patent of the United States #774,458, granted to myself onthe eighth day of November, 1904, although, of course, the plow of thepresent invention may be utilized entirely independently of this or anyother ditching machine.

The invention consists in the improved construction, arrangement andcombination of parts, which will be hereinafter fully described, andparticularly pointed out in the claims.

In the accompanying drawings has been illustrated a simple and preferredform of the invention; it being, however, understood that no limitationis necessarily made to the precise structural details therein exhibited,but that changes, alterations and modifications within the scope of theinvention may be made, when desired.

In the drawings, Figure 1 is a perspective view of a plow constructed inaccordance with the principles of the invention. Fig. 2 is a sideelevation of the same. Fig. 3 is a dptail perspective view of a portionof the p ow.

Corresponding parts in the several figures are indicated throughout bysimilar characters of reference.

The share 1 and the landside 2 of the improved plow converge at thepoint 3. The moldboard M is composed of a plurality of spaced bars 4, 4connected with or formed integral with the landside and curved upwardlyand outwardly on the lines of an ordinary moldboard, so as to be capableof turning a furrow slice in the usual manner the bars 4, 4 aresustained in proper position by means of braces, as 5 and 6, said bars4, 4

being connected with and spaced from the braces 5 and 6, as by means ofstuds 7.

The rear end of the landside is formed with an upwardly extendinginverted U-shaped arch 8 the links of which are spaced apart; said archbeing provided at its upper end a bracket 9 which is suitably connectedwith the beam 10, near the rear end of the latter. A standard 11 extendsupwardly from the landside and is likewise connected with the beam.Handles 12 and 13 are provided, the former of said handles beingconnected directly with the beam, while the latter is connected with abrace 14 extending forwardly to the standard 11, and said handles beingconnected with each other by means of a rung 15; an inclined brace 16connects the standard 11 with the beam; and auxiliary braces, as 17, maybe employed wherever their presence may seem necessary or desirable.

Connected with the lower end of the rear arm 18 of the landside arch 8,as by means of a bolt or pivot 19, is a cutting member 20, the point ofwhich extends forwardly between the front and rear legs or members ofthe arch 8, while the lower or cutting edge of said cutting memberextends beneath the lower edge of the landside, as will be clearly seenin Fig. 2 of the drawings; braces, as 21, are employed to retain thecutting member in operative position. The bolt 19 is provided at itsinner end with an ordinary screw tap (not shown). By loosening the saidtap, the cutting member 20 may be pitched at a desired angle withrelation to the rear arm 1.8 of the arch 8 and, when in such position,the said tap is tightened when the said cutting member is pivotallyfixed in such position with relation to the said arch arm.

A draft rod 22 is provided, said rod being bifurcated at its rear end soas to straddle the standard 11 the fork 23 of the draft rod carries aroller 24 riding upon and engaging the rear edge of the standard.Pivotally connected with the draft rod 22 near the front end of thelatter is a link 25 which extends through a keeper 26 upon the beam 10,near the front end of the latter, said link being adjustable in thekeeper, as by means of a bolt 27; the front end of the rod 22 isprovided with a hook 28 for the attachment of the draft. By thisconstruction the draft will be exerted at a point intermediate the beamand the landside, and excessive strain upon the juncture of the beam andthe arch 8 will thus be avoided.

As hereinbefore stated, this improved plow is specially devised for thepurpose of turning.

a furrow slice, or excavated material, back into a ditch, such as a tileditch, from which it has been excavated. In order to perform thisoperation successfully, it is obviously necessary that the lay orlandside be prevented from swaying laterally under the impulse of thepressure of material upon the moldboard; such lateral movement is inthis case prevented by the cutting member 20 which cuts into and.engages the surface of the soil in rearof the landside and in alinementwith the latter. The arch which separates the point of the cutter fromthe landside proper permits weeds, grass, roots, and other obstructionsto work out gradually, instead of accumulating in front of the cutterand thus interfering with the operation of the device. The draft may beconveniently regulated by the herein described arrangement of the draftrod, which permits the nose or point, of the plow to be'tilted to theproper inclination to cause the plow to penetrate to the desired depth.

The general construction of the improved plow is simple and inexpensive,and it has been found to be thoroughly efficient in operation.

Having thus described the invention, what is claimed is 1. A plow havinga landside, and a cutting member supported in rear of and spaced .fromthe lam side with its cutting edge below the lower edge of the landside.

2. In a plow, a landside having a terminal rear arch, and a cuttingmember connected pivotally with the rear leg of said arch.

3. A plow having a landside, an arch located at the rear terminal ofsaid landside, a cutting member connected to the rear leg of said archand having'its forward end located in advance of the rear leg and in therear of the front leg of the arch.

4'. A plow having a landside, an arch located at the rear terminal ofsaid landside, a cutting member connected to the rear leg of said archand having its forward end located in advance of the rear leg and in therear of the front leg of the arch andits loweredge located below thelower edge of the landside.

In testimony that I claim the foregoing as my own, I have hereto affixedmy signature in the presence of two witnesses.
